@ThePhoenixRisesHigh if i'm being honest, i have no idea. i just started publishing chapters and people found my book. something i'd recommend is reading other's books. most of the times when i see a new vote or a comment on my book i look at the account and read their books if i find them interesting. like, make friends and maybe they will start to read your book. after that even more may find your poetry.
hope you found this answer helpful in any way. <3
